Galvanized Steel Coil Supplier

Galvanized Steel Coil is used cold rolled steel coil as substrates by a continuous hot-dip process. This method tightly adheres the coating to the steel with an iron-zinc alloy bonding layer formed by a diffusion process while the heated steel strip is in contact with the molten zinc. One of the drawbacks of Galvanized is that if the Zinc coating is scratched off the steel, the Steel is left unprotected, and is subject to failure. It has excellent corrosion resistance, paintability, and workability due to zinc’s characteristics. 

Specification

Mechanical Properties

When the nominal thickness of the product is greater than 0.50mm but less than or equal to 0.70mm, the elongation after fracture is allowed to decrease by 2%; when the nominal thickness of the product is not greater than 0.50mm, the elongation after fracture is allowed to decrease by 4%.

Surface Structure

Spangled galvanized steel sheet is the spangle obtained by the condensation of the zinc coating under normal conditions after galvanizing. It is mainly used in buildings and other places where there is little direct contact with the human body.

Galvanized steel sheets without spangles are mainly produced through a special production process to control the lead in the zinc pot to a certain level, or after the strip steel is out of the galvanized pot, it undergoes special treatment to control the spangles to less than a certain level. Mainly used in home appliance housing. 

Hot Dipped Galvanized Steel Coils Prices

The prices of hot-dipped galvanized steel coils depend on zinc thickness, steel coil thickness, packing method. 

Surface treatment of galvanized steel coil

Chromate treatment of galvanized steel coils is also called passivation treatment. Through passivation treatment, the surface structure and gloss of the galvanized layer can be improved, the corrosion resistance and service life of the galvanized layer can be improved, and the bonding force of the coating and the base metal can be improved.

The purpose of oiling galvanized steel coils is a protective layer is formed on the surface of the steel coil to prevent the surface from rusting. 

Galvanized steel Coil Uses

Galvanized steel coil has a wide range of applications, and its advantage is that it has a long anti-corrosion period. It is mainly used for home appliances, office panels, roof sheets, automotive panels, construction and substrate of prepainted steel coils.                                                                                                                                                                                               

Car board

The use of automotive plates must first be stamped and formed, and the steel plate is stamped into the required shape and size of the part.

Then spot welding, as an important welding method for thin plate connection, has a wide range of applications in the manufacturing industry, especially in the automotive industry.

Galvanized roof sheet

The performance requirements of galvanized roof panels mainly include the mechanical properties of the material (tensile strength, yield strength, elongation), coating performance (coating type, coating thickness and coating adhesion)

Home appliance office board

Including air conditioners, washing machines, refrigerators, photocopiers, etc., household galvanized sheets are mainly used for general forming applications and stamping.

Substrate

Another use of galvanized steel coils is to be used as the substrate of prepainted steel coils. prepainted steel coils have polyethylene coatings than galvanized coils and are more durable.
